Utility model content
The utility model aim is to provide a kind of antilock drill bit, and purpose is exactly antilock drill bit master to solve the above-mentioned problems
It is used for cement-soil stirring pile construction, antilock blade design effectively to have blocked first of stirring blade and second stirring blade
Bonding between clay particle, preventing blade, brill phenomenon is embraced in excessive generation pilling since clay bonds, and is reduced lower brill and is promoted and is hindered
Power, making stirring, evenly pile is efficient, high-quality.
The utility model is realized by following technical approach：
A kind of antilock drill bit and its application method, the antilock drill bit include six square joints, drilling rod, and stirring blade is reinforced
Muscle, wear-resisting tile, antilock blade, whitewashing conversion section, upper and lower stirring blade, pick, drill bit, mouth spray, six square joints
It is welded on drilling rod top, the stirring blade right-angled intersection is alternate to be arranged on drilling rod, and the wear-resisting tile is embedded on drilling rod,
The antilock blade is connect by wear-resisting tile bolt with drilling rod, and the pick is mounted on first of stirring blade of drilling rod.
The drill bit expanded diameter is 400~2000mm.
The antilock blade has twice, is arranged in up and down between stirring blade and stirring blade, the antilock blade
It is made of two panels Ω type blades, and is fastened by bolt, is socketed on wear-resisting tile.
There are one circular hole, upper and lower stirring blades to be socketed in drilling rod by conversion section of whitewashing at the center of stirring blade up and down
On, upper and lower stirring blade is freely rotatable, and rotation angle is 0~90 °.
There are two the mouth spray settings, is arranged in drilling rod corresponding with the center of upper and lower stirring blade
On, and in approximately the same plane.
Compared with prior art, it has the following advantages：
1, using antilock blade design, the bonding between twice stirring blade clay particle has effectively been blocked, blade is prevented
Brill phenomenon to be embraced since clay bonds excessive generation pilling, reduces lower brill and promotes resistance, make stirring evenly, pile is efficient,
It is high-quality；
2, it when inlaying high-strength plate tooth, pick on stirring blade, can carry out constructing into rock, stratum wide adaptation range.
3, it is designed using upper and lower whitewashing, cement mortar utilization rate is high, and stirring is evenly.

Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, gives detailed embodiment and specific operating process, but the guarantor of the utility model
Shield range is not limited to following embodiments.
Embodiment
As shown in Figure 1, a kind of antilock drill bit and its application method, the antilock drill bit includes mainly six square joints 1, drilling rod
4, stirring blade 2, reinforcing rib 3, wear-resisting tile 8, antilock blade 5, whitewashing conversion section 6, upper and lower stirring blade 7, pick 9, drill bit
10, mouth spray 11, six square joints 1 are welded on 4 top of drilling rod, and 2 right-angled intersection of the stirring blade is alternate to be arranged in brill
On bar 4, the antilock blade 5 is made of two panels Ω types blade 12, is connect with drilling rod 4 by the bolt of wear-resisting tile 8, described section
Tooth 9 is mounted on first of stirring blade of drilling rod 42.
The utility model designs a kind of antilock drill bit, and application method is：Antilock drill bit carries out soil cement in cohesive soil
When mixing pile construction, entire bit is drilled down into, and the stirring blade up and down 7 for being arranged in 4 lower section of drilling rod is made in soil body resistance
Under, the circular hole at 7 center of upper and lower stirring blade and the mouth spray 11 of lower section are in coincidence status, i.e., the mouth spray 11 is under
It is in open state during boring, is arranged in the stirring blade up and down 7 of 4 top of drilling rod under soil body drag effect, stirs up and down
The circular hole at 7 center of blade and the mouth spray 11 of top are in 90 ° of positions, i.e., the mouth spray 11 in going down process in closing
State, lower section mouth spray 11 continue to soil body jet cement slurries, and the stirring blade 2 is rotated together with drilling rod 4 to the soil body
Cutting stirring is carried out with cement grout, the antilock blade 5 is removed with antilock drill bit one gets into the soil body, due to 5 sets of antilock blade
It is connected on drilling rod 4, under the extruding force of soil, antilock blade 5 is not rotated with drilling rod 4, i.e., with respect to stirring blade 2, antilock blade 5
It remains static, this has effectively blocked the bonding between 2 clay particle of twice stirring blade, prevents blade from being bonded due to clay
The excessive pilling armful brill that generates causes lower brill difficult；Under when getting into a bottom absolute altitude, entire antilock drill bit is lifted up, cloth
The stirring blade up and down 7 below drilling rod 4 is set under soil body reaction force, upper and lower stirring blade 7 reversely rotate 90 °, at this time in
The circular hole of the heart and the mouth spray 11 of lower section are in 90 ° of positions, i.e., the mouth spray 11 is closed in going down process,
The stirring blade up and down 7 of 4 top of drilling rod is arranged under soil body reaction force, upper and lower stirring blade 7 reversely rotates 90 °, at this time
The circular hole at center and the mouth spray 11 of top are in overlapping positions, i.e., the mouth spray 11 is in opening state in going down process
State, top mouth spray 11 continue to soil body jet cement slurries, the stirring blade 2 rotated together to the soil body with drilling rod 4 and
Cement grout carries out cutting stirring, and the antilock blade 5 is promoted with drill bit, since antilock blade 5 is socketed on drilling rod 4,
Under the extruding force of soil, antilock blade 5 is not rotated with drilling rod 4, i.e., with respect to stirring blade, antilock blade 5 remains static,
This has effectively blocked the bonding between 2 clay particle of twice stirring blade, prevents blade is excessive since clay bonds from generating pilling
It embraces and bores and lead to underground drilling accident, continue to be promoted when rotating whitewashing, until pile is completed.
